Polder de Brest: Ailes Marines has selected Navantia to manufacture the foundations of the Saint-Brieuc offshore wind farm.

Brest - 16 September 2019 - Ailes Marines, in charge of the development, construction, installation and operation of the offshore wind farm in the Bay of Saint-Brieuc, has selected the Spanish company Navantia to manufacture the 62 foundations for the offshore wind turbines that will equip the wind farm.

Fabrication of the foundations

The foundation technology used by Ailes Marines is a three-foot jacket type. These are structures in the form of steel wire mesh weighing up to 1,175 tons, for a height of up to 74 meters, fixed to the seabed by piles.

The components of the foundation will be assembled on the Brest polder by the company Navantia on a dedicated area of 11 hectares located to the north of the site.

The complete assembly will take place in Spain and the port of Brest will again be mobilized for temporary storage space before sending the foundations to the site.

Thus, the polder and its "heavy package" quay, as well as the other quays in the port, will be used for reception, prefabrication, logistics and the transport of components.

This open-air site, organized horizontally, will mobilize between 2021 and 2023, a minimum of 250 full-time equivalent jobs over 2 years. Among the trades targeted: welders, oxycutters, handling operators, scaffolders, quality supervisors, among others.

The Brittany Region and the port of Brest are thus contributing to the development of the new industrial sector represented by marine energies.

foot structures

"Ten years; that's how long it took for this offshore wind project to become an industrial reality. To achieve this, the Brittany Region has anticipated the needs of Ailes Marines and built a "marine energy" terminal in line with the sector's expectations. Today, it is pleased to welcome Navantia, which has extensive experience in this field. This project is a founding step in the emergence of the marine energy sector in Brittany. It is a first step that will enable the port of Brest to be positioned as an anchor point for the sector on the Atlantic coast, and no doubt beyond. This stage is also the beginning of a new energy and industrial history for Brittany, for which the relay will be taken by the floating offshore wind turbine which should reach our coasts as soon as possible. »

Loïg Chesnais-Girard

President of the Brittany Region

"The choice of Navantia for the construction of the jacket foundations on the Brest polder is a concrete expression of the industrial commitments announced by Ailes Marines for the construction of the Saint-Brieuc offshore wind farm. Together with the wind turbines, which will be manufactured in the port of Le Havre, this is the second major industrial facility to be launched thanks to the Saint-Brieuc project. We are proud that Navantia is the first occupier of the polder in the port of Brest and brings a minimum of 250 jobs to Brittany. »

Jonathan Cole

President of Ailes Marines, Director Iberdrola Eolien Offshore World

"Navantia and Windar are committed to this important project, bringing their experience and know-how in the field of marine renewable energies, notably by supporting Ailes marines and the Brittany region in their desire to position the port of Brest as a major player in renewable energies in Europe. Navantia is committed to total collaboration with local industries for the development of new activities and jobs in order to contribute to the future of the Brittany region. »

About the Brittany Region and the Port of Brest

Since 2017, the Brittany Region, which owns the port, has been carrying out a major development project to increase maritime traffic and develop an industrial terminal dedicated mainly to marine energy. Over the period 2017-2022, the total investment amounts to €220 million, financed mainly by the Region but also by Europe (ERDF funds), Brest Métropole, the Department of Finistère and the CCI. Over the past two years, earthworks have made it possible to consolidate and develop the current 40 ha polder to accommodate companies. At the same time, the construction of a 400 m long EMR quay and a 900 m dike has been undertaken. These infrastructures have been combined to form a new 14-hectare trap which, once filled in, will extend the polder over a total usable area of 54 hectares by 2024.
